UT27 MB - 800 lumens Trail Running Headlamp

Four light sources, born for running. Three white colour temperatures reaching 168 metres, plus a genuine high-output red beam, in a 74-gram headlamp that runs on USB-C or AAA. Four light sources: three white colour temperatures plus a high-output red 800-lumen turbo reaching 168 metres from twin quad-core MCT UHE LEDs High-output red light, 150 lumens to 70 metres, for red-light-only race sections Colour temperatures: 3000K warm (CRI 98), 4500K neutral (CRI 85), 6500K cool (CRI 73) 74g ready to run, with a reflective sweat-channelling headband HLB1500 USB-C rechargeable pack, or 3 AAA batteries as backup Up to 14.5 hours white runtime and 21 hours on red IP66 weather resistant, with a glow-in-the-dark battery door A red light you can actually see by. Some races run red-light-only sections to protect wildlife and other runners. Most headlamps meet that with a 2 to 10 lumen marker glow that barely lights your feet. The UT27 MB delivers a high-output red beam of 150 lumens that throws 70 metres, across three brightness levels plus SOS and slow flashing. You keep a clear, night-vision-friendly view of the trail and hold your pace where a normal lamp would slow you to a walk. Match your light to the ground, and see true colour. Three white colour temperatures. 6500K cool cuts through distance on fast, open terrain. 4500K neutral suits general running. 3000K warm reads through fog and rain and is gentle on the eyes at camp. High colour rendering, up to CRI 98. A high-CRI beam shows the trail the way daylight does, so wet rock, roots, route markers and your own gear all read correctly. Many headlamps sit near CRI 70 and wash that detail out. 800 lumens and 168 metres, hands-free. A TrueVision+ multi-faceted lens system passes over 94% of the light and blends a wide near-field flood with a focused spot, so you light the ground at your feet and the terrain ahead at the same time. Turbo pushes 800 lumens out to 168 metres for reading a marker, a ridge line or a far bank. Three working levels sit below turbo, from a 100-lumen low that runs 14.5 hours to a 500-lumen high, so the beam fits a quiet campsite or a fast night descent. 74 grams. You forget you are wearing it. Ready to run at 74g with the bracket, headband and HLB1500 battery, and just 48g on its own, the UT27 MB sits light and bounce-free over a long effort. The breathable headband channels sweat away and carries reflective elements so you stay visible on the road or trail. Light enough to stay on your head from dusk to dawn without the front-heavy nod that tires you out on a heavier lamp. WHY THE UT27 MB OVER AN ORDINARY HEADLAMP Red that leads the way A 150-lumen red beam to 70 metres handles red-light-only sections at running pace, where a typical 2 to 10 lumen marker light leaves you crawling. Three whites in one Switch between cool, neutral and warm for the conditions, up to CRI 98, instead of living with one harsh tint that suits half your night. Recharge or refill The USB-C HLB1500 pack covers everyday use, and 3 AAA batteries get you home when you are days from a charger. Wear it anywhere The four-way clip moves it from the headband to a cap brim, a pack strap or a waist pack, and a stuff sack turns it into a camp lantern. Off the head when you need it elsewhere. The included multipurpose clip mounts the UT27 MB four ways: on a cap brim for a lower angle, on a backpack strap, on a waist pack, or back on the headband. The beam goes where you are working, not just where your head points. A glow-in-the-dark battery compartment helps you find and swap the cell in the dark, and the diffusing stuff sack turns the lamp into a soft lantern for a calm camp or post-race recovery. Through the night, on a pack you recharge. The included HLB1500 1,500mAh battery pack charges over USB-C in about 1 hour 30 minutes and runs up to 14.5 hours at 100 lumens, enough for an all-night effort or several evenings out. When you are far from a socket, drop in 3 AAA batteries instead and keep going. The pack swaps in seconds, so a spare gives you a second full night. Built to take the weather and the knocks. The body is moulded from durable, high-strength PC that shrugs off abrasion, impacts and low temperatures. It carries an IP66 rating against rain and dust and survives a 1-metre drop, so a wet race or a fall on rocky ground is no drama. A 90-degree adjustable bracket tilts the beam exactly where you need it, and the wide-opening compartment makes a battery change quick even with cold hands. FOR EVERY KIND OF NIGHT OUTDOORS Trail & Ultra Running 74g and bounce-free, cool light for speed and a real 150-lumen red for red-light-only race sections. Hiking & Camping AAA backup for multi-day trips, a warm beam and the lantern stuff sack for a calm camp, red mode in the tent. Fishing & Wildlife CRI 98 warm light shows true colour at the water or the hide, and red mode holds your night vision and stays low-key. Everyday & Utility Clip it to a cap or pack for hands-free work, with high-CRI light so finishes and fine detail read correctly.

Most headlamps use red only as a low marker glow of a few lumens. The UT27 MB has a high-output red rated at 150 lumens to 70 metres, with three brightness levels plus SOS and slow flashing, so you can hold a running pace through red-light-only race sections and still preserve night vision. Can I run it on normal AAA batteries? Yes. It takes 3 AAA batteries, either alkaline or rechargeable Ni-MH, as a backup for when you cannot recharge the HLB1500 pack. Runtimes are a little shorter on AAA than on the USB-C pack. Older 10400 Li-ion or LFP cells are not supported. Can it be used as a lantern or worn off the headband? Yes. The included diffusing stuff sack turns the headlamp into a soft camp lantern, and the four-way clip mounts it on a cap brim, a backpack strap or a waist pack instead of the headband.
